The Wheel, which comprises the plate, buckets, and hub or shaft-cylinder,when made of cast-iron, is of one piece, each side of which is represented in the annexed drawings, Figures l and 2.

Fig. 2 represents the upper or inner side of the wheel and the dark shades thereon the openings into the bucket-s C. The plate Bis a circular disk of iron about three-eighths of an inch in thickness and thirty-six inches in diameter. A is the shaft-cylinder, thirteen inches in diameter.

The bottom or lower side of the bucket O, Fig. 3, is attached to the plate at a c, where it is about six inches wide, and, descending thence with a circular sweep outwardly, it decreases gradually in width until it terminates at e e, where it is only three inches wide. The sides ot the bucket (one of which is seen at f) are at right angles with the surface of the plate, commencing with a point at a, and

gradually increasing in width to five inches where they terminate at e D. rlhe sides are consequently six inches apart at a a and three inchesat ee, thus making the vent tiveinches.

one on each end of ahorizontal shaft. In the' latter case the buckets on one Wheel must be reversed in their direction.

In constructing a Wheel the dimensions of the plate, buckets, etc., may be increased or diminished in sizeY in proportion to the head of water or the power required.

As the Water in passing through the bucket acquires an accelerated motion., it lessens in,
